K Street powerhouse loses founding partner

K Street heavyweight Mehlman Vogel Castagnetti is losing one of its star partners.

Alex Vogel, who helped found lobby shop a decade ago, will be leaving at the end of June for his new venture, VogelHood Research.

“What a great 10 years this has been,” Vogel said in a statement. “Together, we launched an elite, respected firm and I am proud to have been a part of a great team. I will remain the firm’s champion and friend and I look forward to years of continued collaboration and success.”

The firm brought in $13 million in lobbying fees last year, making it the No. 11 firm on K Street by revenue. Its client roster includes Chrysler, Wal-Mart, Yahoo!, the Mayo Clinic, United Technologies Corp., Blackberry, the American Petroleum Institute, the Technology CEO Council and the Business Roundtable, among many others.

In an email sent on Thursday afternoon, David Castagnetti said that the firm still planned to work with its “buddy.”

“While we will continue to collaborate with him on a variety of things, he’ll be officially leaving Mehlman Vogel Castagnetti to help his new non-lobbying start-up succeed,” he wrote.

Bruce Mehlman, in a statement, added: “Alex is a great friend and has been a valued partner. We know he will achieve a great deal in his new venture.”

As part of the transition and rebranding, the two remaining founders — Mehlman and Castagnetti — have put three others on the firm’s nameplate: Dean Rosen, Kelly Bingel and David Thomas, becoming Mehlman Castagnetti Rosen Bingel & Thomas.

“Over the past 10 years we have a proven track record of success and we look forward to growing both our services and expertise for the next 10,” Castagnetti said in a release.

Rosen held a series of high-profile healthcare roles during his time on Capitol Hill, including as the health advisor to former Sen. Bill Frist (R-Tenn.). In the private sector, he worked for the Health Insurance Association of America.

Bingel has become known as one of Washington's top female lobbyists and held posts in the office of former Sen. Blanche Lincoln (D-Ark.) and within AT&T's in-house lobby shop.
